Abstract
Polymer compositions are described containing a white pigment for increasing the reflectance properties of the resulting material. In this regard, the material is well suited for being used as a reflector, such as a reflector for light-emitting diode assemblies. In accordance with the present disclosure, the white pigment comprises chalk resistance particles. The particles can also display a basic pH when placed in distilled water.
